CHARLES L. HEISLER, OF SCHENECTADY, NEW YORK.

ERASING-PENCIL.

Application filed November 21, 1911.

To all whom it may concern:

Be it known that l, CHARLES L. HnIsLnn, citizen of the United States, residing at Schenectady, in the county of Schenectady and State of New York, have invented cerain new and useful Improvements in Erasing-Pencils, of which the following is a specification describing the device illustrated by the accompanying drawings.

The object to provide an elongated eraser with a r ady means for adjustment; to avoid the necessity of repeatedly replacing a worn rubber remnant; thereby securing convenience and economy in the use oi time, patience and rubber, moreover to provide a more compact and shorter length of pencil for maximum length of eraser and lead, so thdevice may be placed in a pocket or will not project so far therefrom when it is securely held in a vertical position by a suitable fastener.

Figure 1, shows a part exterior side ele ration, and part sectional view with the ex terior casing broken away to reveal a section of the eraser, and exposed exterior portion or the lead holder inclosed by the eraser. 9, shows a sectional elevation oi: the case and inclosed eraser with an exterior elevation of the centrally located pencil holder which is of usual construction and has lead 10, projecting from the lower end thereof. F 3, is an exterior side view of the complete device, illustrating the means for clamping the eraser. that projects from the upper end. The dotted portion shows the position or the clamping ring when it is desired to adjust the eraser, insert, or remove it from the case. Fig. i, is a view taken of Fig. 3, when it is revolved about the axis of the pencil through an angle of 90 degrees. Fig. 5, is a top end view of the eraser shown in Fig. 1. Fig. 6, is a crosssection of the pencil near its middle when fitted with a tubular eraser. Fig. 7, is a cross-section of the pencil when used with two erasers as shown in Fig. 9, and which may be of ditlerent material, suitable for either lead or ink erasing. Fig. 8, shows a cross-section when the pencil is used with a single eraser shown in Fig. 10. Fig. 9 shows two erasers which may be made of different material suitable for either lead or ink erasing. Fig. 10 shows a pencil used with a single eraser. Fig. 11 is an end view of the pencil with the eraser crushed.

The device consists essentially of a slotted case 1, having a lead holder 2, of usual con struction, arranged within the case, in a manner to conveniently project the lead tip 10, from its lower end 3. The means for clamping and adjusting the lead within the holder 2, are not shown, as they may be any one of the well known constructions. Between the lead holder, and. case as shown, is an annular space filled with a movable elon gated eraser l, l, 1 or 4?, which lies alongside the l ad in the pencil and projects from the upper end of the case where it is held by a. clamp 5 or 5, formed thereon by sloting the case as shown at 12 and arranging a ring (3, 3, to slide endwise thereon for the purpose of loosening or tightening the clamp hen ad usting or fastening the eraser by the crushing action of the clamp. A resilicnt finger 7, is formed on the ring 6, for t 1e purpose oi securing the pencil to pocket in the usual manner, and for providing a catch 8, for securing the clamp ring 6, in its upper position as shown. The catch 8, en gages a hexagonal enlargement or bead 9, formed on the case.

1, shows the lead holder 2, extending to the extreme upper end of the clamp 5, which in this figure sh wn of circular cross section to provide a round eraser, shown also in Fig. 5. In Fig. 2, the lead holder is sufiiciently t'oreshortened to permit the clamp to form a that ended eraser which is also illustrated in Figs. 3, 4, and 11. The pencil holder 2, is arranged with the usual means for adjusting the lead tip 10, as it becomes worn or broken. In the device shown this is done by turning the sleeve ll, which causes a longitudinal movement of the lead 10. The detail or interior construction of the lead holder, and means for moving the lead, are not shown, as they may consist of any one of the several well known devices used for this purpose. Evidently other suitable writing material may be substituted for the lead 10, which is to be herein understood to mean any suitable writing material when made into pencil or stick form. Evidently the ordinary forms of eraser can also be used in the clamp 5, when desired. As will be seen from Figs. 2 and 3, the finger 7, is made more resilient and yielding when pressed over a thick hem of a pocket because of the outward elastic pressure of the rubber eraser acting against the clamp 5,'and the bead 9, and finally.

against the catch 8, at the end of the finger 7, the clamp ring 6, being sufficiently loose on the case 1, to permit it to act as a fulcrum. This construction avoids the objection to the lack of resilience in the usual construction of fingers which offer considerable resistance and cause unnecessary efi'ort when pressed over the pocket hem which frequently must be held to aid in doing this.

It will be seen from the drawings that the slotted tubular case 1, is contracted at its lower end to tightly embrace the lead holder 2 near its lead projecting end 3. The slot 12 extends to near the lower contracted end.

Claims:

1. In a pencil, the combination of a casing, a tubular eraser in said casing and protruding from one end thereof, and means for crushing the outer end of said eraser.

2. In apencil, the combination of a tubular casing, a movably mounted tubular eraser protruding from the upper end there- 'of, means for crushing the eraser, a lead protruding from the lower end of the'casing, and a holder'for supporting said lead,

said holder being disposed within the eraserand attached to the lower end of said casing.

3. In a pencil, the combination of a tubular casing, erasing means having spaced parts extending along opposite sides of the interior of the casing and protruding from the end of the. casing, a lead holder held be tween said spaced parts of the erasmgmeans within the casing, and means for presslng into'contact the opposite faces of said parts of the erasing means beyond the end of the lead holder.

4. The combination in a pencil, of a tu 'bular case, a lead-holder mounted within the case, eraser means comprising a soft and a gr tty'portion dlsposed wlthln the case and around the lead-holder, a lead protruding from the lower end of the pencil, and'means to compress the eraser to cause the soft and the gritty eraser portions to come adjacent to each other when both portions project from the upper end of the pencil.

5. In a pencil, the combination of, a case havlng a bead, an eraser protrudlng from one end of said case, a member mounted on said case and adapted to assist in retaining the eraser in place, and a garment engagin device movable with said member and'having a part which cooperates with said bead to retain said device and member near one end of the case whereby the eraser is clamped in the case.

7. In a pencil, the combination of a casing contracted at one end and a slot extending from the opposite end of said casing to a point near its contracted end, a lead-holder within the casing adapted to feed from said contracted end, an eraser disposed in the casing around the lead-holder and protrud ing from the slotted end, a member movable along the outside of the casing and cooperating with the slotted end of the latter to clamp the eraser, and a. device for retainlng said member in a fixed position.
